Pretty well, nothing to report.

Currently trying to upgrade repmgr (distributed PostgreSQL) from 4.0.2 to 4.0.3

Steps:

  1. Upgrade the secondary to 4.0.3
  2. Promote secondary to primary
  3. Upgrade old-primary to 4.0.3
  4. Upgrade old-primary to primary.

This fails on step 2. as the step now (with 4.0.3) requires some features on the primary that are missing in 4.0.2.

This is being discussed as issue 388 (in repmgr github site).

Current plan is to resolve this by "murdering" the primary, forcing the fall-back to the secondary.
